YUKINO TSU Application filed october ia ZZ whom t may concern:

Be it known that YUKrNo Tsn'rflui, a citi- Zell GOUD

of Japan, residing at Seattle. in the ty of King and State of lWashin.O jtonl has invented certain new and useful Imements in Hatpins, of which the tollowing is a specication.

is invention relates to improvements in hat pins.

The principal object of the invention is to provide a hat pin which will be eective to securely holding the hat upon the head of the wearer, and which involves the use of a construction wherein there will be no outwardly protruding points.

A urther object of the invention is to provi de may a hatl pin of such construction that it be permanently attached to the hat, and' one which may be conveniently manipula-ted to secure the hat in position, whereby the hat may be read or be operated ily removed.V

The invention also comprehends improvements in the details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in the claim.

the accompanying drawings:

lig.l 1 is a perspective view of a hat` showingF myl improved pin applied. ig. 2 is a central vertical section of the -hat pin, showing the pin extended in full lines and retracted in dotted lines.

Fig. 3 is a cross section on the line 3-3 oi Fig. 2.

F ig. 4 is a side elevation of the hat pin.

1 indicates a pin threaded at one end as at 2. The threaded end 2 engages the head 3 of an internal cylinder on sleeve 4, the latter fitting in an outer cylinder 5 extending from a disc or base 6. Inter posed between the disc 6 and the head 3 and encircling the pin. 1, is a spring 7, the opposite ends et the spring being secured to the disc and the head . Obviously, the tension oi the spring is such as to normally draw the inner sleeve 4 wit-hin the outer sleeve 5.

The base or disc 6 is ings Ghia lll provided with open- 8, through which extend screws 9, which ge in threaded openings 10 formed disc 1.1.

, 3.922. Serial No. 595,543.

The outer cylinder 5 is provided with .i longitudinal slot 13. having its forward end extended at right angles as at 14 to form a bayonet slot, and fitting in the slot is a pin 15 secured to and 'projecting from the inner cylinder 4.

The discs 6 and 11 are provided with aligned central apertures to form a guideway for the pin 1 clearly shown in Fig. 2.

Assuming that a hat is to be equipped with the hat pin attachment, the hat is first punctured either on one or both sides, depending upon whether or not it is desired to des oi the hat,

have a pin on one or both si the puncture being indicated at 16, as shown in `Fig. 2. The puncture may be formed with the point of the pin. rlhen the attachment is placed on the outside of the hat and the disc 11 is placed on the pin 1 to bear on 'the inner surface of the hat, and the screws 9 are engaged in the openings lO to secure the two discs to the wall 17 of the hat as shown in Figs. 2 and 4. The attachment having now been secured in place, the spring 7 tends to draw the cylinder or tubular extension 4 within the tubular ext-ension 5 in telescopic form, hence the pin 1 is normally held in extended position. To remove the hat from the head of the wearer, the head 3 is gra-sped and the cylinder or tubular extension 4 is drawn outwardly, and with the pin l is retracted against the tension of the spring 7, and iic it be desired to hold the pin in retracted position, the head 3 is git/*en a slight turn to bring the stud 15 into the right angular portion 14 of the bayonet slot. This forms a locking connection and prevents the spring 7 forcing the pin outwardly to extended position.

The cylinder 5 and head 8, as well as the disc 6, may be suitably ornamented and of any approved shape and of suitable material, to lend neatness to the attachment.

As previously stated, one ot the attachments maybe located on each side oi3 the 95 hat if desired as shown in dotted lines in Fig. l.

W' hat I claim is:

A hat pin, comprising a pair of tubular telescopic members, a mounted in one 100 member extending through a. slot formed n the other member for limiting the telescopio movement orn the members and preventing disengagement thereof, e pin secured in one member extending through the other and adapted to be contained n seid members in extended relation, resilient means for normemes Ine-lly holding the members in teleecoped relation to project the pim means for holding the members in extended relation against the tension of the spring, end meane for securing 'the other member to a hat.

n testimony whereof l affix my signature.
